PBM treatment regulates microglial phenotype. A Representative immunofluorescence images of the M1 marker CD86 and M2 marker Arg-1 in microglia cultured in vitro. Scale bar: 20 μm. n = 4. B-C Quantitative analysis of the fluorescence intensity and relative ratio of CD86 to Arg-1. Compared with the CON group, ***p < 0.001; Compared with the LPS group, ###p < 0.001
